Spin-polarized Quantum Transport in Mesoscopic Conductors: Computational Concepts and Physical Phenomena
Michael Wimmer, Matthias Scheid, Klaus Richter
Mesoscopic conductors are electronic systems of sizes in between nano- and micrometers, and often of reduced dimensionality. In the phase-coherent regime at low temperatures, the c…
Extracting current-induced spins: spin boundary conditions at narrow Hall contacts
I. Adagideli, M. Scheid, M. Wimmer +2
We consider the possibility to extract spins that are generated by an electric current in a two-dimensional electron gas with Rashba-Dresselhaus spin-orbit interaction (R2DEG) in t…
Zeeman ratchets: pure spin current generation in mesoscopic conductors with non-uniform magnetic fields
Matthias Scheid, Dario Bercioux, Klaus Richter
We consider the possibility to employ a quantum wire realized in a two-dimensional electron gas (2DEG) as a spin ratchet. We show that a net spin current without accompanying net c…
Magnetic-field dependence of transport in normal and Andreev billiards: a classical interpretation to the averaged quantum behavior
N. G. Fytas, F. K. Diakonos, P. Schmelcher +4
We perform a comparative study of the quantum and classical transport probabilities of low-energy quasiparticles ballistically traversing normal and Andreev two-dimensional open ca…
